(CNN) -- Dr. Rick Sacra, who entered The Nebraska Medical Center three weeks ago with Ebola, was released Thursday.
'The CDC has declared me safe and free of the virus,' Sacra said at a news conference. 'Thank God, I love you all!'
Sacra joked about now being a lifetime Huskers fan as he thanked his medical team, the biocontainment unit team and his friend, Dr. Kent Brantly.
Sacra and Brantly were both infected with Ebola while working in Liberia with the aid organization Serving in Mission. Sacra was treating patients in an obstetrics clinic in Monrovia, and was not working directly with Ebola patients. He said he does not know how he became infected with the virus, but that it's possible one of the women he helped had the disease.
Brantly, who tested negative for the deadly virus after several weeks of treatment in Atlanta, flew to Nebraska where Sacra was in isolation and donated his blood.
Doctors believe Brantly had antibodies that Sacra needed to help his immune system fight the deadly virus.
In addition to the blood transfusion, doctors gave Sacra aggressive supportive care, including electrolytes and IV fluids.
The Nebraska doctors also gave Sacra an experimental drug called TKM-Ebola, which the FDA recently approved for wider use.
The American patients at Emory University Hospital in Atlanta -- Brantly and Nancy Writebol -- were given a different experimental drug called ZMapp, which was developed by the biotech firm Mapp Biopharmaceutical Inc.
Ebola treatment: Does drug offer hope?
Because doctors still know so little about how to defeat the Ebola virus, they said Sacra, as a physician, was a particularly helpful patient. He was able to give detailed reports about his symptoms.
Sacra has done missionary health work for the past 25 years. He had flown to Monrovia in August after learning his colleagues from SIM had gotten sick. Sacra worried Ebola would cause a 'domino effect' on the already vulnerable Liberian health care system and that people with common ailments wouldn't get help.
When Sacra arrived in Monrovia, that's exactly what he found. His wife, Debbie, said there wasn't a single pair of latex gloves to buy in the entire city.
Without protective equipment, medical clinics shut down. She says Sacra drove from hardware store to hardware store looking for boots to protect his staff.
When he was finally able to open the clinic, for some it was too late. She says dozens of pregnant women who needed Cesarean sections turned up at the clinic after having failed to find help anywhere else in the city.
By the time these women arrived at Sacra's clinic 'only the mothers' lives could be saved,' Debbie Sacra said.
